You're right -- a lot to learn. Especially if you're planning to suppress it.
You'll need a replacement locking piece. The #17 specifically. With the #17 swapped into the bolt group, you'll be unable to shoot it without the suppressor. I am planning on getting my SR9 threaded for a suppressor.
My plan is to get an entirely separate bolt group, along with a second carrier as well. Pricey, but since disassembling the bolt group is a pain and not something I'd want to do at the range, as second complete BCG with the #17 locking piece installed will allow relatively pain-free switching from suppressed to unsuppressed function.
The roller lock game is pricey, even for clone-worlders.
